Semiconductor device and display device

Disclosed herein are liquid-crystal display (LCD) touch screens that integrate the touch sensing elements with the display circuitry. The integration may take a variety of forms. Touch sensing elements can be completely implemented within the LCD stackup but outside the not between the color filter plate and the array plate. Alternatively, some touch sensing elements can be between the color filter and array plates with other touch sensing elements not between the plates. In another alternative, all touch sensing elements can be between the color filter and array plates. The latter alternative can include both conventional and in-plane-switching (IPS) LCDs. In some forms, one or more display structures can also have a touch sensing function. Techniques for manufacturing and operating such displays, as well as various devices embodying such displays are also disclosed.

PROBLEM TO BE SOLVED: To provide a display device and an electronic equipment in which high added-value is realized by installing a display screen on the front and the rear, and moreover, size reduction, thinning, and turning light-weighted are realized. SOLUTION: The display device and the electronic equipment are provided which have either one of a structure of a structure, wherein a substrate provided with a light-emitting element making lower-face emission and a substrate provided with the light emitting element making upper-face emission are pasted together, and a structure, wherein substrates provided with the light emitting element making lower-face emission are pasted together two sheets. Since the two substrates provided with the light-emitting element are pasted together, display screens are installed on both front and rear sides, thereby, high added-value is realized. Furthermore, out of the two substrates provided with the light-emitting element, one of the substrate serves as a sealing substrate for the other, thereby size reduction, thinning and turning light-weight are realized. Furthermore, since the pixel parts provided on the front and rear share a controller circuit and a power supply circuit, the size reduction, turning light-weight, and cost reduction are realized.
